“If a woman living with her husband makes a vow or obligates herself by a pledge under oath
and her husband hears about it but says nothing to her and does not forbid her, then all her vows or the pledges by which she obligated herself will stand.
But if her husband nullifies them when he hears about them, then none of the vows or pledges that came from her lips will stand. Her husband has nullified them, and the LORD will release her.
Her husband may confirm or nullify any vow she makes or any sworn pledge to deny herself.
But if her husband says nothing to her about it from day to day, then he confirms all her vows or the pledges binding on her. He confirms them by saying nothing to her when he hears about them.
